Hey guys/gals,

I was discussing with a few mates of mine who reckon they know a fair bit about cars in general (one being a mechanic, one who has worked in workshops for a few years, and one who knew enough about cars to replace a whole clutch at 12 yrs old) anyway we were discussing the axle tramp on my car and how i have been reading about the engine mounts being one of the problems with the axle tramp and how replacing a damaged drivers side mount with a poly mount would keep the engine from bouncing around and causing tramp...

They all said that the engine mounts have absolutely nothing to do with axle tramp or drive train issues(traction ect)

I am after comments from anybody who reads this post. Thanks members.

I read the post and have a comment.

If it bothers you replace it, but youve seen mine and my car still runs so meh.

I dont think this was helpful.

Stuffed mounts will cause rough idleling and maybe vibrations through the car, but i can't see why they'd cause it (not to say they don't though, i'm no mech :P).
Axle tramp i've found is usually caused by factors like tyres, suspension and weather.

Engine mounts absorb the vibration and movement of your engine.. This stops the rest of your car/chassis from rocking or being rough.

Engine mounts dont really play a part in Axle tramp at all.

Tyres and suspension setup are the primary factors for this.

All of the above is IMO (for those that dont understand this :P )

:bowrofl:

Just add it into your signature.

I have also heard theories of axle tramp being caused by not enough power to spin the wheels fully... is this the case? Does anyone have evidence of the cause(s) of axle tramp and evidence of what cures it?

I was talking to a mate the other night and he owns a Lancer... He says he doesnt get much of it at all... and he has told me he lights up the wheels full smoke... Why would he not experiance tramp and i do. My car has a significant power and torque advantage over his car.... The only mods on suspension is a pedders lowered kit...

In a FWD car, broken engine mounts can cause axle tramp because the broken mount allows too much engine movement.
When attempting to break traction, this will cause the engine to "wind up" (ie, movement to the extreme in one direction allowed by the broken mount).
As soon as it breaks traction, the engine will typically move in the opposite direction, causing a weight shift, and affecting traction.
The engine then will often "bounce" backwards and forwards in this way.

Reducing the engine movement with new mounts may not eradicate axle tramp completely, but will certainly help to reduce it.

Cheers,
Martin.

Engine mounts can definitely attribute to axle tramp.

Ok, thanks for the information guys. Problem is, some of you say it doesnt, some of you say it does.....

Can anyone provide proof on either account? Not in theory evidence, but hard proof. lol

Replace the engine mount and see if it helps? It's damaged anyway so it needs to be done eventually.
I'm not going to go out and bust my engine mount just to see if it makes my car axle tramp lol.

lol

But the point of this thread was to find out the real casuse of it if it had nothing to do with the engine mounts, so i didnt spend $110 and get the new mount and find out it doesnt make any difference with tramp.... I want rid of the problem but only want to spend the money on things that will eliminate the problem, not experiment with something that im unsure about.

What suspension do you have on it at the moment?

your mate with the lancer is probably running on slicks now, thats why he doesnt get tramp.

i find its from tyres that are too hard. they dont grip properly. also, if your rear shockies are stuffed, then when you accelerate hard, it will bog down at the back more than it should, which takes weight of the front which then yadda yadda yadda tramp.

to easily remove axle tramp, just dont plant it hard off the line, wait until your at about 10k's using mild throttle, then go it. if you feel the need to floor it, bring the clutch out a little slower with higher revs.

Stock 4 by 4 suspension off a pajero... in other words stock magna suspension... lol

How old are the shocks and springs do you know?

My car axle tramped with the crappy Bridgestone's on it and stock suspension. (no busted engine mounts)

My car axle tramped with Bridgestones + superlows. (no busted engine mounts)

My car axle tramped with Goodyear Eagle F1 GS D3's + superlows (no busted engine mounts)

The point im trying to make is, the car didnt have enough torque to have the wheels slip enough to keep them spinning - hence axle tramp.

I can get axle tramp in my XR6T if i dont floor it hard enough (if i want to spin the wheels)

Auto's will do it more than Manuals as you cant control your revs like a manual.

I always got tramp before I replaced two torn and two cracked mounts. After that I never got it, and that was before any mods to the suspension. That was proof for me, but mine is a manual.

mine is manual as well.

So here we have again, two opinions with evidence, but both with different outcome... this is so ghey.... lol

But its interesting about the xr6T and axle tramp.... My mate has a VR commadore and that dont get it... so yer....

oh well, sh!t happens..

My driver side upper engine mount was replaced recently with a non genuine replacement part. It did seem to reduce axel tramp a little but did not eliminate it. I have found tyre pressure will have an affect. Lower the pressure the less tramp. My car is a manual sports with plenty enough power to fully spin up one wheel, so i dont think its a power thing as my car does it under light trottle or full throttle. It does tend to axel tramp less when the roads are wet.

I replaced an engine mount in my car, and found it to help eliminate axle tramp.
Didn't get rid of it totally, but it doesn't happen as much now.

Mine tramped like a MOFO when I had buggered mounts. Replaced them and it still tramped...but I had to try VERY hard to do it. Now they're worn again and it's starting to tramp again more often.

My point is that they're definitely a contributor...but not the entire cause.
